           Summary: new-run-webkit-tests low timeout is too sensitive to
                    runaway processes or test crashes
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mjs at apple.com


new-run-webkit-tests has a much lower default timeout than run-webkit-tests.
This makes it extremely sensitive to runaway processes, since anything going on
in the background will make a bunch of tests time out. One extra bad factor is
that crash logging for a crashed test (ReportCrash) can cause a system to get
slow enough to time out a bunch of tests in a row, or even time out a
DumpRenderTree process (whereupon it is restarted from scratch).

Thus, the low timeout can actually make overall test time longer instead of
shorter.

I suggest matching the old timeout initially, and changing it over time once we
solve these problems.
